Original application filed October 12, 1905, Serial No. 282,384. Dividedand this application filed January 22,1906. Serial T0 0]] whom, it mayconcern.-

Be it known that .l, FRANK A. NELSON, a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Automobiles; and Ido hereby declare the/following to be a full, clear, and exactdescription of the invention, such will enable others skilled. in theart to which it appertams to make and use implements during theiroperation, as well as to perform other services. 7

It consists of the constructions, combinations, and arrangements ofparts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is.

a side elevationof my said invention. Fig. 2 is a detail, partly inelevation and partly in section, of a cultivator-tooth and of the sleevein which it is mounted. Fig. 3 is an enlarged detail side elevation of aportion of said invention, showing the steering-Wheel turned at rightangles to that view of said wheel which is shown in said Fig. 1 and Fig.4 is a top plan view of said invention, partly broken away. i

In the drawings, 1 is the main frame or body of the traction portion ofsaid machine, which is mbuntcd at one end upon the drivewheels 2 of anysuitable construction and at the opposite end upon the steering-wheel 3.

. Supported in-any suitable manner upon said frame is an engine of anysuitable character or COIIStIUCtIOII ELS, for example, asteamengmeeomprismg the boiler 4 and the en'- gine proper, 5. It is notthought necessary.

to describe the details of the engine, since any of many forms ofengines well known to the art are availablelfor this purpose. Journaledin suitable bearings upon said frame is a shaft 6, provided. with acrank-arm 6, en-

gaging a pitman 5 connected to the pistonrod of said engine. Slidablykeyed or splined to said shaft are 0 osite ears 7 and 8 re spectively,spaced apart and .held in fixed re Said yoke is attached ,to a fixedanchorage of any suitable character, as at 10, by a pair of links 11 and12, one of which is pivoted to said yoke,

and the other to said anchorage, their respeetive opposite ends beingpivotaily connected together. Pivotally connected to the copivoted endsof said links is a lever 13, wl'iich at its opposite end is pivoted to asecond lever 14, which is pivoted intermediate of its ends, as at )5, toa fixed support and is pivoted at its oppo'siteend to a draw-rod L6.

Said draw-rod is pivoted at its opposite end to a lever 17, which isadapted to be manually operated. By operating said iever 17 in onedirection said gears are forced in. one direction along .said shaft, and

by operatingsaid lever 17 in the opposite direction said gears are movedin the opposite direction along said shaft, interposed between saidgears and adapted to be engaged by one or the other of them, accordingto the position in which they are for the time being held by said linksand levers, is a gear 18, fixed on a shaft 1 9, journaled in anysuitable hearings on said frame. Said shaft 19 is provided at itsopposite end with a gear or spur wheel 20,. engaging a gear 21, fixed tothe rotatable axle 22, upon which latter shaft the said drivewheels 2are fixed. It is obvious that with the engine operating continuously inone direction said drive-wheels may be driven in one or the otherdirection, according to which of said gears 7 or S is made to engagesaid gear 18, or said drive-wheels may be deprived of power by holdingthe lever 17 on center, at which time neither of said gears 7 e 8 willengage said gear 18. y

J ournaled in any suitable bearings or in said frrnne,,,as at 23, is adepending fork 24, provided with a bracket 25.

gear-Wheel 26, and'betwcen the tines of said fork is positioned asteering-wheel 27, preferably provided with an annular central flange 27on itspcriphery. .liotatably mounted in any suitable manner on saidframe is a belt-wheel 28, adapted to rotate a pinion 29, engaging saidgear 26. Said belt-wheel is preferably a sprocket-wheel an d is drivenby'any suitable form of bolt--as, for cxample,'tl1e sprocketchain. belt30, engaged by a loose pulley 31', mountedv on said shaft 6. A clutch 32is slidably splined or keyed on said shaft 6 and is adapted in operationto engage said loose ulley to operate the same. Said clutc, is adaptedto be operated or retracted by one Journaled on the post or shank ofsaid fork is a crating clutches for such nil-poses.

Supported in hearings in said racket L 3 is a shaft 34, provided at eachend with pinions engineer or machine t)])(lti )1,'lll theyiemity and 36,respectively. Upon the rotalabl axle of said steering-wheel fixed a gear37, which is eng god by said pinion 3G, wbili said pinion 3. engagessaid gear 26. it will now be obvious that )OWtl may be transmittedfronrsaid shat 6 to said steering wheel through said belt-wheels, gears,and 2 pinions without regard to the direction in which saidsteering-wheel is turned. post of said frame 24 preferably projectsabove said frame, and a lever or tiller 38 is l l l l rigidly mounted onthe upper end of said post for turning said fork.

This tiller is preferg ably provided with a segmental peripherallygrooved guide-tongue 38, to the center of which is secured a tiller-rope39, which (2ntends in opposite directions and around suitableguide-wheels '0 to the hhaft or drum ll of the hand steering-wheel 41.Thus by proper operation of the lever or levers 2533 power can becommunicated from the engine to the steering-wheel 27 to make ittractive, and by mani 'iulation of the wheel ell said Wheel 27 can beturned in any suitable direction to steer the machine, whether saidwheel 27 be tractive or not.

Attached to the frame 1 in. any suitable manner is a frame 42, providedwith crossframes 42. justa-ble with relation to the frame 2 and ispreferably provided with suitable raclgs, 43, adapted to engage pinions44, fixed on a shaft 45, which is journaled in suitable circularbearings 46, extending from said frame 1. Said shaft 45 also. extendsthrough verticall -slotted bearings 47, extending from said frame 42.Said shaft h) also carries a goanwheel 4S, iixed thereto and adapted toengage a worm 49, which is operated by a shaft 50, which provided at itsopposite end with a gear-wheel 5i, interposed between twos' 'iaced gears52 and 53, mounted on said shaft 6. Said gears and 52 are spaced apartand held. in proper relation to each mg annular grooves in theirrespective hubs.

end of a link 55, which is pivoted at its opposite end to one arm oi aJell-crank lever 56.

Said lever 56 is pivoted intermediate of its 't'ain of levers in whichthe lever 58 is in cluded the mechanism. may be operated to traifisnntpower from the engineto said gear id to raise or lower tlie forward. endof said frame r as desired, The rear end of said frame t! is preferablycarried on. a caster or Said frame 42 is preferably ad-,

other and to said gearol by a yoke 54, engagf V I or truninnitted toother machines. Said yoke 54]. is pivotally connected to one l l ltrailing wheel 61 of any suitable construction mounted in bearings 62,carried by said frame 42.

A seat (i3 is preferably provided for the sary to micro particularlyillustrate or describe theili. i

Said cross beams or frames 42 are preferably of flanged construction andadapted to support sliding boxes or bearings (36. The webs of saidframes 42 are preferably apertured at intervals to receive pins, as 67,extei'iding through the boxes (36 and through the in'ipleinentpost, as68, of whatever.

Said posts 68 may be aperlnred at intervals, so; that eachimplement may be .indepemle'ntly adjusted in said boxes. may behorizontally adjusted as desired, according to the space desired betweenfurrows or otherwise. it is obvious that any suitable grou int-workingimplement having a suitable suspending-post may be inserted in saidboxes instead of such cultivators. I. do not, therefme, desire to belimited to the use of such eultivators in said machine, but othersuitable implements (not shown) may be used therein or therewith withinthe spirit and scope of my said invention.
